by mesne assignments, to Addressograph-Multigraph Corporation, porationof Delaware Cleveland, Ohio, a cor- 53 Claims.

This invention relates to printing machines of the type in whichindividual printing devices are successively passed through printingposition, and the salient object is to distribute im- 5 pressions fromdiiierent parts of each printing device in transposed relation on asheet and to distribute the impression from successive printing devicesin columnar relation on the sheet.

Another object is to provide a printing ma- 10 chine in which the sheetis movable in correlation with the impression operation.

Still another object is to arrest the printing device movement duringthe time impressions are made from different parts thereof.

15 A further object is to indicate the positioning of certain printingdevices in printing position; and an ancillary object is to indicatecertain operating conditions in the machine as when the last line on thesheet moves from printing position.

A still further object is to provide a printing machine in which thedistribution of the impressions from different parts of a printingdevice on a sheet may either be manually or automatically performed.

Further objects of the invention are to simultaneously impartlongitudinal and transverse movement to the sheet to effect movement ofthe sheet in a diagonal line; to control longitudinal movement of thesheet by a member movable into varied positions whereby the longitudinalmovement may be varied; to employ a platen embodying sectionsrespectively alined with separate groups of printing characters on theprinting devices whereby the platens may be selectively released toprint a separate group of printing characters; to impart a step-by-stepmovement to the sheet to space the lines of printing charactersimprinted thereon and to M effect this spacing upon predeterminedshifting of the sheet transversely of the machine; to interruptoperation of the machine when the supply of printing devices in theprinting device magazine is exhausted; to afford variation in thetransverse movement imparted to the sheet; to

yieldably interconnect the operating and operated parts of the machineto thereby prevent injury to the operated parts under abnormalconditions and avoid injury thereto; to effec- 5Q tively clamp the sheetin the lister to prevent relative movement between the lister and thesheet; to disconnect the printing device feeding mechanism duringpredetermined operations of the machine; to selectively determinewhether 55 or not impressions are to be made from the printing devicespassing through the machines and to maintain the timed relation betweenthe various operating parts when impressions are not made from selectedprinting devices; to determine transverse shifting of the sheet from theprinting devices; and to time the operation of control devices in themachine so that operation thereof will be effected at the end of a cycleof operation of the operating mechanisms.

Referring to the drawings, I indicates the main frame on which. thevarious instrumentalities of my improved machine are mounted. The frameis mounted on casters 2 and supports the bed plate 3. A bracket 4 on themain frame supports an electric motor 5, the driving pulley 6 of whichis connected by a belt 7 to a pulley 8 fixed on the shaft 9 jcurnaled inthe frame 1. Another shaft I9 is journaled in the frame i and has aflywheel pulley I! thereon connected by a belt 12 to the pulley l3 fixedon the shaft A clutch structure of the type commonly employed inmachines of this kind and generally indicated by M connects the flywheelpulley ii to the shaft iii. A lever I is pivoted on the frame I and theoperating rod it of the clutch structure Hi is attached thereto. Asolenoid ii of approved form mounted on the frame i operates the link i8connected to the lever 55. When the push button switch 59 (Fig. 2'!) isclosed the machine is set in operation since this closes the circuit tothe solenoid H from the line wires 2!! and El, the main switch 22 havingbeen previously closed. The switches i9 and 22 are conveniently locatedin the machine. The switch it need only be momentarily closed sincemeans, to be described hereinafter, including the link 23 attached tothe lever i5 holds said lever in operating position during normaloperation of the machine. A link 24 operated by a crank '25 on the shaftit is pivotally connected to the main operating member 25 at 21 andimparts rocking movement to said member The member 25 is pivotallymounted, as indicated at 28, on a lug depending from the bed plate 3.The various instrumentalities of the machine are operated from the mainoperating member 25 and these instrumentalities function to perform theprinting operations at predetermined places on the sheet 29 which isarranged on the bed plate 3 in the following manner:

As best shown in Figs. 2 to 6 inclusive, a guide bar 30 has one endthereof fixed in a supporting bracket 52 and the other end thereof issupported by an auxiliary bracket 3i. Mounted for movement along theguide bar 3% is the lister slide 33. An adjustable arm M is mounted formovement in the lister slide 33 and is retained in adjusted position bythe thumb screw 35, Fig. 10. At the outer end of the arm E i is asupporting arm structure 35 on which a substantially channel-shapedclamp plate 31 is mounted. One edge 38 of the channel-shaped plate restsin a groove 39, Fig. 4, in the bar it, secured plate 4|.

to the outer end of the arm 34, of the arm structure 36. Secured to theunder side of the bar 4%] and projecting forwardly therefrom is a flatplate 4! having a groove 42 therein in which the edge 43 of thechannel-shaped plate 3! is rested. Extending upwardly from the bar 43through the plate 3! are bolts M. Disposed around the bolts 44 betweenthe heads thereof and the plate 3'! are coil springs 45 which, incooperation with the fiat springs 46 at the end of the arm structure 35,urge the plate 3'! downwardly. A locating stud i'i is mounted at one endof the bar 40 and projects therefrom. The sheet 23 is abutted againstthe locating stud 41 and the adjacent edge 48 of the bar it when it islaid over the A block 59 is pivotally mounted at 5| on the upright 52extending from the bar 40. A grip member G9 includes a foot portion 53secured to the clamp plate 31. During the insertion of the sheet 29 theedge 43 of the plate 31 is elevated by moving the grip member 49 topivot the plate 31 about the edge 38. Since: the sheet is inserted whenthe edge 43 on the plate 31 is elevated, it is apparent that when thisedge is lowered a portion of the sheet will be forced into the groove42, Fig. 5, by this edge 43 and will be very effectively clamped by thespring pressure exerted on the plate 31. As best illustrated in Fig. 6,the brackets 3i and 32 are respectively mounted on rollers 54 and 55 formovement transversely of the bed plate 3.

In Fig. 25 one form of sheet to be printed in the machine isillustrated. This sheet is indicated by 29a and the printing operationsimprint indicia thereon in vertically alined relation. In the presentinstance, a portion of the indicia is imprinted in the vertical column51. Other indicia is imprinted in the vertical columns 53. The indiciain the columns 5'! and 58 is transversely alined and this transverselyalined indicia is imprinted from characters on the same printing deviceor plate 59, Fig. 21. Two rows of printing characters 50 and GI areprovided on the printing devices 59. Above the rows 58 and BI anotherrow of printing characters 62 is provided. Indicia is imprinted on thesheet 25m in the columns 58 from either the row 55 or iii while theindicia in the column 51 is imprinted from the characters in the row 52.

The printing operation is performed by socailed snapping platens whichare retained in a cocked position against spring pressure. Releasing ofthe platens from cocked position enables the carrying out of theprinting operation in a forcible manner. This platen construction willnow be described. Extending upwardly from the bed plate 3 is a bracket53, Figs. 2 and 14, and extending laterally across the machine from theupper end of the bracket 63 is a tubular supporting member 64, Fig. 28,having, at the outer end thereof, the platen arm 55. Mounted at the endof the arm 55, Fig. 2, is a platen housing 66.

The arm 55 is connected to the member 64 in the following manner. Asleeve 61, Fig. 12, unitary with member 54, has a flattened portion 69and, bearing against this flattened portion, is a plate it secured tothe end of the arm 55 by the bolts ii. A slight clearance between theplate iii and the end of the platen arm 65 perunits the plate to bedisposed angularly to the end of the arm by varying the position of thebolts ll. adjustment thus provided is employed to bring the lower end ofthe platen housing, and the platens mounted therein, into parallelrelation with the bed plate 3 and the printing devices movable throughguides in said bed plate.

At the ends of member 64 are retaining nuts 68. Extending through thesleeve 61 is a shaft I2 to one end of which an arm I3, Fig. 1, issecured. Pivotally connected to the outer end of the arm I3 is a link I4pivotally connected at I5 to an arm I6 pivotally mounted on the supportfor the main operating member 26, Fig. 28. On the arm I6 is a pad I?that rests on the abutment I8 on the frame I. A pawl II' engages ahardened portion I8 on the arm I6. The pawl is pivotally mounted on theoperating member 26 and is urged upwardly by the spring I9 intoengagement with the roller 89' on the arm BI carried by the shaft 92pivotally mounted in the abutment I8. The shaft 82' is moved, in amanner to be set forth, to dispose the roller either in the notch 83' oron the rise 84'. When the roller 89' is in the notch 83 the pawl engagesthe portion I8. Upon movement of the main operating member 25, in acounter-clockwise direction as viewed in Fig. 1, by the link 24. thepawl 11 engaging the portion I8 moves the arm IS in a similar direction.This moves the arm I3 upwardly and this movement is transmitted throughthe shaft I2 to the arm I9, Fig. 14, mounted on the shaft I2 at the endopposite the arm I3 and this arm I9 moves downwardly upon such movementof the arm I3. Downward movement of this arm I9 selectively operates theplatens in the following manner:

Guides 68, Fig. 13, in the platen housing have vertical grooves thereinin which the platen slides 80, 8! and 82 are slidably mounted. Springanchors at the upper ends of the slides: have springs 83, 84 and 85,Fig. 12, secured thereto, the other end of said springs being connectedto the spring anchors 86 on one of the guides 66', Fig. 15. The springsurge the platen slides downwardly. The platen slides are retained inupper position by the pawls 81, 88 and 89, Fig. 12, seated in notches insaid slides and mounted on shafts 99, 9I, and 92, that extend outthrough a wall of the housing 56. Substantially L-shaped arms 93, as,and 95, Fig. 14, are mounted on these shafts exteriorly of the housing66. Rods 96, 91, and 98, have corresponding ends thereof pivotallyconnected to corresponding ends of the arms 93, 94, and 95,respectively. The opposite ends of the rods are extended throughopenings in the flange 99 on the end of the arm I00 (Figs. 6 and 14)mounted on the shaft IIII journaled in the sleeve :92 (Fig. 12) carriedby the lug I93 depending from the arm 65. In a manner to be set forthpresently the arm I00 is moved to selectively aline the ends of the rods96, 91 and 93 with the stud IM at the outer end of the arm H35 of thebell crank I06 (Fig. 14) pivotally mounted at I 01 on the arm 65.Springs I08 extend between the housing 66 and the ends of the arms 93,94 and 95 and urge the ends of the rods 96, 9'! and 23 through theopenings in the flange 9% and these springs also urge the pawls 87, 82and 89 into retaining position.

A spring I99, connected to the arm I95 of the bell crank I95, urges thestud Ifl i away from the ends of the rods 96, 9'5 and 2 3 and thisaction is limited by engagement of the arm N9 of the bell crank I06 withthe stop III on the arm 65. Unitary with the arm Hi3 is a boss H2 havinga set screw I53 mounted therein. The set screw II3 engages the lower endof the pawl I Id pivotally mounted at H5 at the outer end of the armIII). A spring HE is disposed between the pawl H4 and the boss II2 abovethe pivot H5 and urges the portion of the pawl below the pivot intoengagement with the set screw H3. The nose II1 of the pawl H4 isdisposed in the path of the pad I I8 on the arm I9. As the arm I9 movesdownwardly in the manner previously described the pad II8 engages thenose II! and moves the pawl and bell crank as a unit to force the studI94 into engagement with the rod alined therewith. If, for example, therod 95 is alined,

I the arm 93 is pivoted and movement of this arm rotates the shaft 99attached thereto. This shaft 99 rotates and moves the pawl 8I from thenotch in the platen slide 80. At the lower ends of the platen slides theplatens Ils are mounted and when the pawl 81 is retracted, as set forth,the spring 83 moves the platen slide 86 downwardly and the platen II9connected thereto bringsabout a printing action in a manner to be setforth. Similarly, if the rod 91 is pushed the platen slide 8| isreleased. If the rod 93 is pushed the platen slide 82 is released in themanner above set forth.

As shown best in Fig. 15, each of the platen slides has a recess I29 inthe lower edge thereof across the open end of which the platens H9extend. Through an opening I2 I, Fig. 12, in the flange portion of thearm 65 another arm I22 is extended which arm I22 includes an enlargednose portion I23. The arm I22 extends through the recesses in the platenslides and the nose I23 is disposed in the recess in the intermediateplaten slide 8|. On the outwardly disposed platen slides 80 and 82 padsI25, Fig. 13, are secured which extend into the recess I29 in the platenslide 8| on each side of the pad E24 disposed in this recess andconnected to platen slide BI. The sleeve I92 is fixed in lug N33. Thearm I22 is pivotally mounted on this sleeve. An arm I26, Fig. 14, isalso pivotally mounted on the sleeve 12, and the arms I22 and I25 areconnected. The end portion I2! of arm I26 is disposed in the path of theroller I28 on the arm I9. The pad II8 on the arm 19 has been describedas engaging the nose II 2 during its downward movement and after this.engagement has continued for a period sufficient to cause actuation ofone of the rods 95, 97, or 98, the pad II8 disengages the nose I I1. Asthe arm I9 continues: to move downwardly or clockwise, as viewed in Fig.14, the roller I28 engages the end portion I2! of the arm I26 andturnsthis arm in a counter-clockwise direction. This movement is transmittedto the arm 422 and causes this arm to be moved upwardly into engagementwith the pad I25 or I24 of the released platen, and the released platenis elevated as the arm I22 continues to move upwardly. As soon as thepad IIS disengages the nose I I! the spring I69 retracts the arm W5 and,therefore, the stud I94, which permits one of the springs I98 toreposition the shaft 9e, 9!, or 92, and the parts carried thereby, thathave been moved. Therefore, one of the pawls 8i, 83,or 89, seats in thepreviously released slide and retains this slide in its upper or cookedposition thus tensioning the spring 83, 9 or connected thereto.Operation of the machine is so timed that immediately after the arm i252has restored the previously released platen slide the main operatingmember 26 starts to more in the opposite or clockwise direction, asviewed in Fig. 1. The arm I5 has a boss M, 1A, thereon that is disposedbehind a boss 25' on the main operating member 26. The clockwisemovement of the main operation member engages the boss lit with the boss14' and the arm it is moved. This rotates the shaft T2 in acounter-clockwise direction, as viewed in Fig. 14, which disengages theroller I28 from the end portion IZZZ and as the pad lit engages the noseIll the pawl Ilfil pivots about the mounting ill") against the action ofspring H5 and thus the bell crank N36 is not moved. Disengagei lent ofthe roller I25 from the end portion permits the arm H252 to fall.Downward movement of the arm I22 is limited by engagement thereof withthe pad its, Fig. 12, on the upper edge of the block 83% fixed to thehousing 65. In this position the arm I22 is disposed with the nose i213thereof below the pads lit and H35 and engagement of a pad therewith,when a platen is released, limits downward movement thereof. In theforegoing manner each of the platen slides may be selectively andaitomatically released to bring about a printing operation andsubsequently restored to inoperation position.

The printing devices or plates 58 are arranged in a vertical stack in amagazine 29 positioned at the rear of the bed plate 3, Fig. 2, and fromthis stack the bottom devices are successively withdrawn and carriedforward along the guideway lild, Figs. 2 and 24, to the anvil I3I, Fig.22. The printing devices are taken from the stack and fed forwardly inthe guideway by the reciprocating feed bars I32, Fig. 11, positionedbelow the guideway ltii and reciprocal toward and away from the anvil l3I. Feed pawls its on the feed bars I32 engage the rear edges of thedevices 59 that are in the guideway ififi and when the bar isrecip-rocated the rearwardmost pawls engage the lowermost printingdevice in the magazine I29 and carry this device into the guideway. Asreciprocation of the bars 6 is continued the pawls successively engagethe rear edges of the device, during the forward portion of thereciprocating movement, the pawlsfreely passing under the printingdevices during the rearward portion of the reciprocating movement, andthus the printing devices are advanced through the guideway in astep-by-stepmanner. The feed bars I32 are operated from the lever I34,Figs. 1 and 11, which has an extension arm E35 thereon that rocks thelever tilt through the link Ii'l connecting these members. The lever H36is mounted on a shaft ltd journaled in a portion 539 depending from thebed plate 3. One arm of the bell crank Mt, fast on the shaft 538, isconnected by a link I lI to the feed bars I32. The other arm of the bellcrank has a notched end Mil engaged by the spring urged trigger Hi3mounted on the arm I44 of the lever I35, the spring urging the triggerinto the notch. An arm l id, Fig. l, on the operating member 25, has alink Hil connected thereto and is also pivotally connected to the leverass at use. When member 26 moves in a counter-clockwise direction, asviewed in Fig. 1, movement is imparted through arm ME, link Ml, leverE34, arm its, to lever liitl, through trigger i 23, bell crank I lh, tolink HM, to move the bars i132 rearwardly. As the operating member movesin a clockwise direction, as Viewed in Fig. l, the movement istransmitted as above to lever and, the pin his engages the arm of thebell crank M5 to which the link It! is connected and, in this manner,the bars I32 are moved forwardly.

In the machine as illustrated the printing devices are advanced on yduring alternate operations. To this end I provide the ratchet I41,Figs. 11, is and 19, and the push rod M8. The ratchet l ll is mounted ona shaft ass journaled in the frame l and has a plurality of teeth on theperiphery thereof. The teet on the periphery of the ratchet i il are soarranged that they effect the alternate feed of the printing devices andtherefore the teeth are alternately deep and shallow, the deep teethbeing indicated by the while the shallow teeth are indicated by ltii.However, if a different advancing movement is to be imparted to theprinting devices as a different arrangement of the deep and shallowteeth is provided, the particular arrangement depending upon theparticular ad- Vance movement to be imparted to the printing devices. Astep-bymtep movement is imparted to the ratchet It? in synchronism withthe main operating member 2%. The mechanism for doing this includes theU-shaped bracket I52. that is best illustrated in Fig. 19. The bracket5532 is supported from the shaft I69 by a casting hit. The rightangularly extending end portion of the rod M8 is extended across thebracket 552 in juxtaposition to the bight portion thereof, and the endof the portion I54 is adapted to seat in the teeth ldll and I5I, Fig.14. The bracket 952 has a lug IE5 at the upper end of one arm thereofwhich lug lies in the path of the stud use on the pawl I51, Figs. 14 and28, pivotally mounted on the rocker I58. On the pawl iii? is a stud 59seated in a. socket itll in the arm Eiil pivotally mounted on rocker Aspring Hi2 extends between the pawl i i? and arm Mil and urges arm Itlinto engagement with the stop pin E65. The lever I34 is a part of therocker H53 and when the link it? first actuates the lever Hit, therocker I58 is moved with. the shaft its, Figs. 12 and 28, on which it ismounted, in a clockwise di ection, Fig. 14. ment with the lug l 2' onthe casting carrying bracket I52, id, and movement is imparted throughthe bracket H52 and the portion 54 to the ratchet M7, and the ratchet ismoved in a counter-clockwise direction, as viewed in Fig. ll. Pivotadymounted on the frame is a retaining pawl iiii Figs. 14 and 19, normallyengaged in the teeth of the ratchet Ml by the spring When the pawl itsis seated in the teeth of the ratchet, as depicted in Fig. 19, and whenthe ratchet is moved in the manner above set forth, the pawl ltd ridesover the teeth and prevents movement of the ratchet in the oppositedirection. In this manner the step-by-step movement is imparted to theratchet it? and, therefore, the portion Hi l is alternately disposed ina deep or shallow tooth. When the portion lii l is disposed in a deeptooth I50, as illus trated in Fig. 11, the end of the push rod I48 isretracted from engagement with the trigger M3 and this trigger remainsseated in the notch M52 as shown in Fig. ll. However, when the portiontilt is disposed in the shallow tooth I5I, the end of the push rod weengages the trigger and unseats the trigger from the notch M2.Therefore, when movement is imparted to the lever no movement isimparted to the bell crank by reason of this disconnection. Since thedeep and shallow teeth are alternately arranged and, as a step-by-stepmovement is im- '75 This moves the roller I58 into engagepins I82 may bemounted.

parted to the ratchet I41 in synchronism with the operation of the leverI36, it is apparent that the trigger I43 is alternately seated andunseated and, therefore, movement is imparted in a, rearward directionto the feed bars I32 only on alternate operations of the machine and,therefore, the printing devices 59 are only advanced upon alternateoperations of the machine.

In the operation of machines of the character to which this inventionappertains, it is often desirable to print from only certain ones of theprinting devices, but it is also very desirable that the order of theprinting devices not be interrupted. It is, therefore, customary toprovide tabs I66 on the printing devices which may be engaged by asuitable detector arrangement. The printing devices are arranged in themagazine I29 in the usual manner and are successively fed throughprinting position, but only certain of the printing devices are used ina printing operation because of the mechanisms, to be described, whichprevent printing operation. These mechanisms are controlled by the tabs166 which may be disposed in difierent transverse locations on theprinting devices 59, as is well understood. Further, the machine isarranged to either print or fail to print from the printing deviceshaving tabs in certain positions, and the construction which enables theaccomplishment of this includes the shaft E61, Fig. 20, journaled in theframe. A rockable member, generally indicated by I68, includes atransverse portion 59 from which bearing portions I10 are extended thatare mounted on the shaft I61. An extension I1I of one of the bearingportions of the member I68 has a cam member I12 pivotally mountedthereon. A spring I13 interconnects the extension HI and the member I12.Fast on the shaft I38, carried by the depending portion or lug I39 is arocker I15 which includes a. roller I16 that travels on the cam surfaceI11 of the member I12. When the shaft I38 is turned with the bell crankI40 the rocker I15 is oscillated and thus the roller HE is caused totravel over the cam surface I11 to pivot the cam member I12, thusstretching the spring I13. When the spring I13 is stretched the portionI59 of the member I68 is urged upwardly. On the portion IE9 is a platemember I89 which has a plurality of holes ISI therein in which verticalThe vertical pins I82 include substantially right angularly extendingend portions I83 which are disposed below the printing devices or plates59, Fig. 21. The pins I82 are alined with the tabs E56. If, therefore,when the portion 569 moves upwardly one of the portions I83 engages atab 568, the upward movement of the portion I59 will be arrested. Abifurcated post member IB i, Figs. 15 and 20, is mounted in the frameand a lever I85 is pivotally mounted therein. Extending outwardly fromthe portion IE9 is a pin E85 on which the reduced portion I81 of thelever 53% is rested. When the portion W9 is permitted to move upwardlyin an unrestricted manner, as when an end portion i23 does not engage atab- I66, the pin I86 engages the end portion !81 and moves this end ofthe lever E85 upwardly while the opposite horizontal bifurcated end E68is moved downwardly. If, however, the member IE9 is held againstmovement by the engagement of an end portion I83 with a. tab I56, it ismanifest that the spring 13 will a erely be stretched, upon movement ofthe cam member I12, and,

or on the flattened upper surface of the arm ESQ. A projection $84 iscarried by the member its and has blades 3% and I96 extending above theupper edge thereof providing a pocket I91.

A downwardly depending arm I98 on the member iiiil is disposed betweentwo stops I99 and 200, Fig. 14. When the rod I92 is moved downwardly bythe action of the lever I85 the member its will be rocked, thus rockingthe projection its and the blades I95 and I953.

Pivotally mounted on the frame is an arm 23! which carries at thelowermost end thereof a pin 282, Fig. 20, that is arranged to cooperatewith the blades I95 and I98 and the pocket 81. At the upper end of thearm 2M is a lug 2&3 which lies in the path of the nose 204 on the pawlE51. When the pawl Iiil is moved in the manner set forth heretofore thenose 2! engages the lug 203 and pivots the arm Zlll to elevate the pin282. If therod I92 is not moved the pin 262 will be free to move intothe pocket I21. However, when the rod I92 is moved, either the blade I95or I96 will be moved into position below the pin 202 and this pin willbe prevented from entering the pocket I91.

Suitable means are provided for shifting the rod l92 either into or outof the recess I9I. When the rod is in the recess IS! the member I89 willbe disposed so that the end of the lug 5% will, under normal conditions,engage the stop I99. The shifting of the rod W2 is emplayed toaccomplish either the printing or the failure to print or, as it iscalled, skipping, of the printing devices having tabs, such as laid,thereon, and this printing operation is controlled in the followingmanner:

An arm 205 is connected to the arm SI and has an end portion which restson the pin 2&2. When the pin 2G2 engages either of the blades I95 or I96and the pin 202 is prevented from downward movement the arm 205 willserve to hold the roller 36' on the rise 84. When the roller 80' is heldon the rise 8d the end of the pawl 11 will be held from engagement withthe hardened portion 13, Fig. 1 on the arm 15, but when the pin 202moves into the pocket I91 the arm 2535 will permit the roller 86' to bepositioned in the notch 83 and, therefore, the end of the pawl 11' willengage the hardened portion 18'. When so engaged, the arm 16 is movedand, as has been previously brought out, this arm 15 controls the platenoperation and, therefore, the printing operation. Thus when the pin 2E2engages either the blade 95 or I95, the printing operation is prevented,but when it moves into the pocket 591 the printing operation will becarried out. The particular use of this arrangement in the machine willbe set forth hereinafter.

On the operation of the machine following the printing'device feedingstroke, when the machine is arranged for duplicate printing operatiens,it is necessary that the pin 202 not be displaced. Therefore, when theportion 555 is in a shallow notch I5I, the roller I56 rides on lug I55and holds the nose 234 from engagement with lug 203 and, therefore, arm21H is not moved.

An arrangement is provided for interrupting the operation of the machinewhen the last of the printing devices 59 has been removed from themagazine I23. This arrangement includes the lever 236, Fig. 1, pivotallymounted on the frame. A bell crank, generally indicated by 201, Fig. 24,includes an arm 238 having a foot portion 209 which extends through theside of the magazine I29 into engagement with the printing devicesstacked therein. The arm 2!!! of the bell crank 201 has a rod 2Hextended through the free end thereof which rod has an enlarged head 2I2at the upper end thereof. A spring 2I3 is disposed around the rod 2Hbetween the arm 2H! and the head 2H2. The lower end of the arm 2H isbent to extend at right angles to the main extent thereof, and this bentportion, indicated by 2M, is extended through the end of the lever 206.The other end of the lever 223 is bifurcated, as indicated at H5, and aroller 2H5, Fig. 1, on the free end of the arm I18, is disposed therein.The arm I78 is connected to the link I41, as indicated at I18, and whenthe link I41 is reciprocated, in the manner set forth, the roller 2l5will move through the bifurcation 2I5 and reciprocate the lever 236 tomove the rod 2 II vertically. The downward portion of the movementimparted to the rod 2 causes compression of the spring 213 which willact on the arm 2H3 of the bell crank 20'! to urge the foot portion 209toward the printing devices 59. However, as long as there are anyprinting de vices 59 in the magazine, the foot portion 229 is preventedfrom inward movement and, therefore, the vertical reciprocation of therod 2H merely causes alternate compression and expansion of the spring2I3. A pivotally mounted dog 2 I1, Fig. 24, has a latch 218 extendingtherefrom. A spring 2I9 acts on the dog 2!! to urge the latch 2I8 intothe position shown in Fig. 24 wherein it is shown as being positionedabove the bar 22! The rod 23, Figs. 1 and 24, is connected to the bar223 and when the lever I5 is moved downwardly to start the machine, inthe manner set forth, the movement is transmitted through the rod 23 tothe bar 220, and this bar is moved downwardly and the latch 2!!! movesinto position thereabove, as illustrated in Fig. 24, to prevent upwardmovement of the bar 223 and, in this manner, the machine is held inoperation. However, when the foot portion 239 pivots inwardly and doesnot engage at least one printing device in the magazine I23, the setscrew 22 I, carried by the arm 253 of the bell crank 26?, engages thestud 222 on the dog 2!? and pivots the dog to move the latch 2E8 fromposition above the bar 223 which permits this bar to move upwardly and,manifestly, this upward movement of the bar 220 imparts similar movementto the rod 23 which permits the lever I 5 to move upwardly and thusinterrupt operation of the machine.

Mounted on the stud 222 is an arm 223 having a notch 224 thereinadjacent the lower edge thereof. A spring 225 acts on the arm 223 tonormally hold this arm in the position illustrated in Fig. 24. Connectedto the lower end of the arm 223 is a link 226. The other end of the link226 is connected to the armature 221 that is pivotally mounted at thelower end of the magazine, as indicated at 228. A magnet 229 is providedand, when this magnet is energized, in the manner to be set forth, thearmature,22l is attracted and the movement thus imparted is transmittedthrough the link 226 to the arm 223 and this arm is moved against theaction of the spring 225 to position the notch 224 below the projectingnose 23!] of the arm 2%. Therefore, when the arm 225 is moveddownwardly, during normal operation, in the manner previously set forth,the projection 23!) seats in the notch 224 and the arm 223 will be moveddownwardly which moves the dog 2H to move the latch 2! from retainingposition. The spring 225 normally holds the notch 224 from alinementwith the projection 23!]. The spring 2I9 acts on the dog 2|! at alltimes and, therefore, as soon as the lever I5 is moved downwardly, whichresults in similar movement being imparted tothe bar 220, it is manifestthat the latch 2I8 moves into retaining position which is illustrated inFig. 24.

The devices which clamp the paper and associated mechanisms constitutethe means to bring about the proper distribution of the printing on thesheet 29. These mechanisms comprise the brackets 3I and 32, the tubularsupport and the lister slide 33. This lister slide is movable along thesupport 30 to move the sheet 29 to bring about the vertical spacingbetween the various transverse rows of indicia. is carried out at thetime the sheet is arranged to receive impressions in the column 5'! andis accomplished in the following manner: on the bracket 63 a bearing23!, Fig. 28, is provided in which a shaft 232 is journaled whichincludes a right angularly extending portion having a roller 234 at thelower end thereof. On the end of shaft I2 opposite the arm 19 is an arm235, Fig. 1, which includes a nose portion 235. On the arm 238, mountedon the shaft 232, is a stud 231. When the shaft 12 is operated in themanner previously set forth the arm 235 is moved and the nose 23Ethereof engages the stud 231 to move the arm 238, shaft 232, and theroller 234. When. the machine is ar ranged to bring about the imprintingof the indicia in the column 5"! the spacing mechanisms are alined withthe roller 23 1, as illustrated in Figs. 2 and 3. These spacingmechanisms include the racks 239 and 260 slidably mounted in thebrackets 3| and 32 and extended through the lister slide 33. The rack239 has square teeth 24! provided therein, as best illustrated in Fig.6, and will be referred to hereinafter as the locking rack. The rack 259has ratchet teeth 242 provided therein, as best illustrated in Fig. 10,and this rack will be referred to hereinafter as the spacing rack. Theforward end of the spacing rack 24!] is tapered, as indicated at 2 53,Fig. 6, and the roller 234 bears against this tapered end.

The ends of the racks 239 and 24B, opposite the ends adjacent the roller234, extend through a recess in the bracket 32. A block 22!, Fig. 10,supports a stud 244 which extends through a projection 240' on the rackwhich projection extends past the block 2%. The'r'ack 239 is securedtothe block 24I'. A coil spring 245 Is disposed about the stud 244between the head thereof and the projection 2 58'. When the roller 234is moved, in the manner set forth, during engagement with the end 243 ofthe spacing rack 223, the spring 245 is compressed. In the lister slide33 a pawl 226, Fig. 10, is slidably mounted which is urged into seatingen- This spacing gagement with the teeth 242 by the spring 2&1. When therack 2% is moved in the manner set forth, this pawl are rides over thebeveled portion of the tooth in the rack 249 which it has been engagingand then drops behind the shoulder of the succeeding tooth. During thistime the lister slide Si is held against movement by the seating of thepawl 2%, Fig. 6, in the teeth 2M of the locking rack 239, said pawlbeing urged into such engagement by the spring 2%. As best illustratedin Fig. 10, a recess 25%; is provided in the upper edge of the rack 23%rear-- wardly of the teeth $22. A roller 25!, mounted on the pawl 252,seats in this recess. The pawl 252 is mounted on the rack 2 122. Ahearing 253, Fig. 3, is provided on the bracket 39 and a bearing 254,Fig. 3, is provided on the casting S2. A rod255 is rotatably mounted inthese hearings 253 and 25 i. Secured to this rod 255 is a pin 256, Fig.'7, which rests on the upper edge of the pawl 252. When the spacing rack2 56 is moved by the roller 234 to compress the spring 245 the roller25! rides out of the notch 25d and moves the pin 255 upwardly. In therod 255 a groove 25'! is provided and a collar 25%, Fig. 4, carried bythe lister slide 33, and through which the rod 255 is extended, has apin 259 thereon which travels in this groove. Connected to the collar258 is an arm 2% which extends through an opening 26L Fig. 4, in thelister slide 33. The arm 260 also extends through the notch 262 in theside of the pawl 2&6, Fig. 1D, and into the notch 253 in the side of thepawl 2 1% Fig. 6. When the pin 256 is raised in the manner set forth,the rod 255 is rotated and, therefore, the collar 258 and the arm 2%.The arm 2% is moved sufficiently to withdraw the pawl 2A3 fromengagement with the teeth 24! and, following this, the lister is movedtransversely, in a manner to be described, to disengage the end 243 ofrack 240 from the roller 23%. The pawl 246 is seated in the teeth 2&2,as the above described movement of the arm 26! does not unseat thispawl, and therefore the lister slide 33 is moved forwardly when thespring 2% is permitted to expand which follows the above describeddisengagement or the end 243 from the roller 23 3. The expansion of thisspring moves the lister slide 3! a distance equal to the length of onetooth on rack 24%. As soon as the spring 245 has expanded sufiicientlyto move the spacing rack 240 in the above described amount, the roller25I reenters the notch 25b and the pin 25% is lowered. This permits thearm to drop and the pawl 248 reseats in a tooth 25!. Therefore, theracks are disposed similarly to the disposition thereof prior to themovement imparted to rack 24B by roller 234. The foregoing operationmoves the lister slide in an amount sufficient to provide proper spacingbetween the transverse rows of indicia on the sheet 25a. Inasmuch as thespacing depends upon the spacing of the teeth in the racks, it ismanifest that different spacing may be easily secured by substituting,for the racks 239 and 2 55!, other racks having different tooth spacing.

In order to distribute the printing in either of the columns. 5'! or 53the lister structure is shifted transversely of the machine to similarlyshift the sheet 29. This is done in the following manner: A bearingstructure 2 54, Figs. 1 and 16, supports a shaft 2'55 about which asieeve 26% is arranged. A bevel gear segment 26? is secured on thesleeve 265. The bearing structure 2M- includes a sleeve bearing 258,Fig. 16, in which a shaft 255! is journaled. Fixed on the shaft is abevel gear segment 21% which meshes w n the bevel gear segment 261. Oneend of a link Eli is pivotaliy connected to the gear segment 2%, asindicated at 212, Fig. l. A spring e:=:- tends between the link 21! andthe frame oi the machine and urges the link upwardly in order that therecess 274 therein will fi about the stud 215 on the main operatingmember MD. This provides a safety arrangement as the link Eli will moveto disengage the recess 2M from stud 2'55 if the mechanisms operated byfi'ii should jam. When the main operating member 25 is moved in ti ocounter-cloclm se direction, as viewed in Fig. l, as previouslthismovement is transmitted through the link 2i! to the gear segment 21!! toimpart movement to the gear segment 261, the gear segments 2h? and as?being moved from the position illustrated in Fig. 1 into the positionillustrated in Fig. 6. Mounted at the upper end of the sleeve 265 is abracket 216 on which a pawl E'i'i, Fig. 18, is pivotally mounted. Thepawl 2?? is urged toward the disk lit, Fig. 17, by the spring iii}, Fig.13. Diametrically opposed notches 28d and 23! are provided in theperiphery of the disk 2'58 and the pawl 2' may be alternately seated inthese notches. During the time the main operating member 26 is moving ina counter-clockwise direction as described the gear segment 252 is beingmoved from the position illustrated in Fig. 1 into the positionillustrated in Fig. 6, and the bracket 27% will be moving in a clockwisedirection, as viewed in Fig. 18. Referring to Fig. 18, when the bracket215 is moved, as above, the pawl Ell is. withdrawn from the notch 2stand moved over the periphery of the disk 2'ii3 until said pawl seats inthe notch 2853. When the main operating member 25 starts to move in theopposite or clockwise direction the gear segment 26'5 is moved from theposition illustrated in Fig. 6 int the position illustrated in Fig. andduring this movement the bracket 2% moves in a counter-clockwisedirection, as viewed in Fig. 13, and, by reason of the engagement of thepawl 2?? with the shoulder or the notch 23s, the disk 2'68 is moved.Mounted above the disk are is a disk 282 having a diametrical dovetailslot 233 therein. A. slide 285 is adjustably mountein the dovetail slot283 and the connecting member 285 is pivotally mounted on one end of theslide 234. A rod 286 is attached to the connecting member 285 andsuitable connecting means 28'! interconnects the slide 282 and the freeend of the rod 285. The slide 288 is slidabiy mounted in the block 289,Fig. 6, carried on th of the machine, 'saidslide 288 being movabletransversely of the machine. By reason of the arrangement including thepawl 2W it is manifest that, upon a complete operation or the mainoperating member 26, the slide 288 is moved in one direction and on thesuccessive complete operation of the main operating member 26 the slide288 is moved in the opposite direction. In the casting 32, an openingFig. 7, is provided in which a sleeve 29! is arranged. A pin 2&2 isfitted in the sleeve 29! and includes an enlarged portion 293. A spring294 is fitted about the pin 2% between the enlarged portion 293 and thelower end of the sleeve 29? and urges the pin 292 downwardly to positionthe lower end or" said pin in the notch 2% in the slide Therefore, whenthe slide 238 is reciprocated, in the manner set forth, and when the pinsee is seated in the recess 295 it is apparent that the
